The Life Cycle of Our Sun

The gas heats up as more materials gather.

Gravity gathers a swirling cloud of gas and dust in space.

After billions of years the core will shrink and the atmosphere will expand.

After millions of years the core will collapse to the size of Earth and the atmosphere is released.
